Ubuntu 16.04, I ran into this issue once before and fixed it by just rebooting the box and rebuilding. However, I have other important servers running on this box so I cannot do a hard reboot at this time.

Without full details of your system, such as the complete output of df -h, df -ih, the full logs from a failed rebuild, and probably a bunch of other things, you’re going to be on your own here. Psychic debugging is such a tiresome process.

Possibly I don’t know, it’s just a stock server from OVH. I was having these issues back when the only thing installed was Discourse. I dunno, this docker & bundler inception is way over my head, other than these weird build problems everything works great though.

I’m really impressed with your commitment to support, thanks for offering to help.
